Precautions Check
Care must be taken to properly size the hydronic heat pump for its intended use.
Prolonged full output run time, over-sizing or under-sizing, and incorrect flow rates can
lead to increased maintenance costs, equipment stress and premature failure.
□
Exposure to corrosive chemical fumes such as chlorinated and/or fluorinated
hydrocarbons can reduce the life of a hydronic heat pump. Cleaners, bleaches, air
fresheners, refrigerants, aerosol propellants, dry-cleaning fluids, de-greasers, paint-
removers and airborne chlorides such as those released with the use of laundry
detergents are to be avoided.
□
Exposure to salt air can reduce the life of a hydronic heat pump. Ocean-front installations
are to be avoided.
□
Locate the hydronic heat pump's base at least 12" [30 cm] above the highest anticipated
snow line. An after-market permanent platform or wall mounting bracket may be used.
□
Locate the hydronic heat pump where water from the defrost cycle will drain freely and will
not cause a slip hazard under freezing conditions.
□
Do not install where operation noise may cause a disturbance.
□
At a new construction site, or during renovations, protect the hydronic heat pump from dust
and other construction related contaminants. Do not seal case openings directly when
operating- allow for air circulation and ventilation in the immediate area.
□
Ensure that the pressure relief valve is installed. It is recommended to pipe relief discharge
into glycol fill tank. Make sure the relief valve outlet is piped with unobstructed piping
(minimum ¾" diameter) to a safe discharge location.
